To all whom it may oonoev' n; I

Be it' known that :I, JoHN H. BA MER, a citizen of the United States ofAmerica,

and resident of Maplewood, llftll county ofEss'e: and Sta te of NewJersey; have invented afn'ew" and Improved Anchoring "Shank forBathroom" Fixtures, of which thefollowing is"afull,"*c 1ear, and exactdescription.

This "IIIVGHtlOIf relates to-'--anchor1-'ng- "deserted in a recess orpocket formed in the :bathrobnrwall' and maintained in place by'emb'ednient m a -c'ementit1ous substance within the pocket'or recess;

One *ofthe outstaiiding' objects of "the "invention is to provide animpr'oved anchor ing *slia'nk for fixturesformedor shaped inf suchjamanner "as' 3 to "provide means when embedded 'ina-pocket or 'recess'in a wall filled with a cementi'tious substance whicli"-willfirmlymaintain the fixture in place when the substance 'is set and hard--ened.

As a further object the invention comprehends an anchoring shank whichis so constructed as to facilitate the emplacing or embedment of theshank in the pocket or recess filled with the substance.

More specifically the invention embodies an anchoring shank formed withtransverse binding grooves within which the ocmentitious substance isreceived to form a key to positively preclude accidental displacement.

lVith the above recited and other ob}- jects in view, reference is hadto the following specification and drawings in which there is exhibitedone example or embodiment of the invention which is in no way intendedas a limitation upon the scope of the appended claims as it is to beclearly understood that variations and modifications which properly fallwithin the scope of said claims may be resorted to when found expedient.

In the drawings Figure 1 is a view in perspective of a bathroom fixturehaving an integrally formed shank constructed in accordance with theprinciples of my invention.

Fig; 2 is aside view of"thesame showing the shank embedded in cement.

integrally formed with thebase *of 'the I nxture.

Referring to thedrawings' by characters reference 1 designates thebaseof adixture which in the-presentinstance is illustrated as atowel barpost or brack t eluding an=arin 2"and a socket 3. The fixture attaching"means consists "of an anchoring shank 4t projecting rearwardly from thecenter of the base 1 which shank is in'the nature of a fru'strumofa'pyramid; that 1s, being of gradually i creasing siae' from thereduced end 5 atthe' juncture with'the' base to its outer 'free end.Extending "longitudinally ot the'fshank and formed in opposite "facesthereof, are' arouately shaped grooves 6 which decrease-in depth fromthe outer free end 7 of the shank to a point'adjacenttheinner reducedend 5. Thelen'gth of the-grooves is'such that they terminate short ofthe morltlnbr opening of thepocket or recess-8 formed in the wall 9.It'will'benoted'that'whilethe opposing outer"surfaces of the wallsof therelation to the recess, that the grooves 6 converge in the samedirection so that the cementitious material C is wedged or urged towardthe mouth or open end of the recess or pocket 8 as the shank is forcedinwardly.

In order to provide means for further retaining the shank in anchoredrelation within the cement filled pocket or recess, the opposing facesof the shank provided with the arcuate grooves 6 are also provided withtransversely disposed binding grooves 10 and 11 intersecting the grooves6 and disposed in staggered relation so that the groove 10 is locatedadjacent the free end of the shank while the groove 11 is locatedadjacent the inner terminus of the arcuate in fiat contact with theouter surtaceot the wall. In some instances however where it isdesirable the outer face of the base may be brought into flush relationwith the outer surface of the wall by enlarging the recess or pocket atits outer end for this purpose. It is of course to be understood thatthe pocket or recess 8 is of sutlicient depth so that when the fixtureis properly positioned the inner free end 7 ol the shank will be spacedfrom the inner wall of the recess.

The cementitious material fills the binding grooves 10 and 11 and whenset or hardened produces the keys K which positively precludedisplacement of the fixture. ine keys thus formed together with thearrange ment of the larger end of the anchoring shank innermost sets upa double locking action which eliminates any possibility of locseness ofthe shank when the usual shrinkage of the eementitious material orsubstance occurs.

I claim:

1. An anchoring device for fixtures comprising a shank connected to afixture and in the shape of a trustrum of a pyramid, the free end ofwhich having a larger cross sectional area than the end secured to thefixture, a pair of the opposite sides of the shank being provided withgrooves transversely disposed 0t said shank and grooves formedlongitudinally of the shank and decreasing in depth from the tree end otsaid shank to points adjacent the attached end.

2. An anchoring device for fixtures comprising a shank connected to afixture and in the shape of a. frustrum of a pyramid, the free end ofwhich having a larger cross sectional area than the end secured to thefixture, a pair of the opposite sides of the shank being provided withgrooves transversely disposed of said shank and grooves formedlongitudinally of the shank and decreasing in depth from the free end ofsaid shank to points adjacent the attached end, one of thelongitudinally disposed grooves crossing the transverse groove, theother longitudinal groove terminating at the other transverse groove.

3. An anchoring device for fixtures comprising a shank connected to afixture, said shank being provided with a. transverse groove adjacentits free end and a transverse groove adjacent its attached end andlongitudinally disposed grooves adjacent the transverse grooves and incommunication with the transverse grooves.

4. An anchoring device for fixtures comprising a shank adapted to beconnected to a fixture, the free end of the shank being longer than theattached end, said shank being provided with spaced longitudinal groovesand transverse grooves extending across the longitudinal grooves.

5. An anchoring device for fixtures comprising a shank adapted to beconnected to a fixture and provided with transverse grooves disposed instaggered relation.

6. A fixture having a base, a shank projecting from the base and havingits tree end of greater cross sectional area than the attached end, saidshank having a groove disposed upon an opposite side of the longitudinalaxis of the shank and running transversely of said axis.
